'The launching apparatus comprises four supporting uprights 1 (of Which tivo are shown) which are hinged at 2 to blocks 3 ailixed to the deck 4, said uprights carrying Weighted latches 5 engaging pins 6 pro Angle plates 7-7 a are aiiixed to the upper extremity of each of said uprights and extend above and beneath pins 8 projecting from the retaining bars 9 (of which one is shown), said pins having enlarged heads 10 which bear against theouter edges of said plates and the latter being connected by removable bolts 11, these ele-ments serving to prevent accidental rotation of the frame Vupon the pedestal hereinafter described.

The boat 12 is supported -above the deck of the vessel by a steel beam 13 having` rollers 13a disposed beneath the center line of the hull intermediate braces 9 and riveted at 14 to a plate 15 Which is pivotally connected at 16Vto the compressed head of revoluble cylinder 17, the rear portion of beam 13 being permanently secured at 13b to an extremity of the retaining braces 9 which are curved inwardly opposite the stern of the boat so as to meet said beam. One extremity of beam 13 is formed integral with an arm 13c provided with a depending internally threaded lug 13 d which Vis engaged by threaded rod 18 projecting through stui'ling box VV19 from the interior of the boat and rotated by means of Wheel 20, While the oppof Samana-11 offertes faena frateljteaualysa, '1919.

The boat is entered through hatches 38 by aid of 'ladders 39 aiixed to braces 9 and' beam 13, said hatches being hinged at 40 to the base of funnel 41 and locked by sliding bolts 42 which engage the cover 43. lNithin said funnel is an air-inlet tube 44 supplied With a close itting cover 45 lined With rubber or other like material from which depends a square cut rod 46 terminating in a clamp apertured for the reception of the enlarged head of threaded rod 47 rod 46 being retained against rotation by its projection through a square opening in disk 48 supported'by braces 49 and rod 47 extending through a threaded boss 50 fixed to the cover 43.

By reference to Figf2 it Will be noted that funnel 41 communicates With pipes 51 which extend transversely across the cover fia . so long as lingers 5,3 rest upon the bottom of places therein, bolts 11 are Withdrawn from` .angle plates 77a so as to release the retainingbars 9 from uprights 1 and the latter are lowered upon the deck of the vessel. Latch 22 is then raised, beam 211 is lowered andthe boa't, together With bars 9, supportfing beam V'13 and cylinder 17, isthen turned upon pedestal28juntil beam 24C depends over the-sideiofthe vessel. During these preparations the boat isniaintained'iii horizontal position by straps 36l and arm 37 in engage- Vment'with lever32, and precipitation of the boat into the Water is accomplished Lby dis- `V engaging rod 18 from lug 13d, the Withdrawal ofthe pin carried by arm 37 and fp-rotation of pinion 34 by crank 34 so as to force upward the rear end of lever 32 and 'thus tilt beam 13 upon pivot 16 sufficiently toI cause the boat to move forward upon the `rollers aiiiXed to said beam and beam 24.

Having thus fully described the several elements ofiiiy invention andthe operation vices for operating said lever against said fralneto tilt the samelongitndinally upon release of saidfmeans preparatory to launching said boat.
